How cold was the ice age? Researchers now know

A University of Arizona-led team has nailed down the temperature of the last ice age—the Last Glacial Maximum of 20,000 years ago—to about 46 degrees Fahrenheit (7.8 C).

The last survivors of the end of the world

(Phys.org) —In 2 billion years' time, life on Earth will be confined to pockets of liquid water deep underground, according to PhD astrobiologist Jack O'Malley James of the University of St Andrews. The new research also ...

Forecasting elections with a model of infectious diseases

Forecasting elections is a high-stakes problem. Politicians and voters alike are often desperate to know the outcome of a close race, but providing them with incomplete or inaccurate predictions can be misleading. And election ...

Climate models make too hot forecasts of global warming

Data from NASA's Terra satellite shows that when the climate warms, Earth's atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to "believe."

Ocean acidification prediction now possible years in advance

CU Boulder researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected ...

Cities attract hurricanes

Five years ago, Hurricane Katrina slammed into the Gulf Coast, devastating New Orleans and other regions along the Mississippi River Delta. Hurricane forecasting has steadily progressed over the intervening years, which should ...

NASA study adds a pinch of salt to El Niño models

When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity—or saltiness—data significantly improves model accuracy, according to a new NASA study.
